Here's a third alternative, and if you remember DOS this third option will be immediately helpful: ZtreeWin. It's the latest Windows version of Xtree Gold, and it really is gold, because Windows search has always been very weak. In fact, in Win7 and following you'll be lucky to find anything at all. Most of the searches I ran in Win10 resulted in 'Can't find anything', even though I was looking right at the location. That's because BING took over the search even on your local data on your machine, and BING is a pile of bull.
But for $30, I can download ZtreeWin, which still has the same interface as XtreeGold for DOS (which I still use on my DOS machines), and it finds EVERYTHING. You want to find text in a file spanning a 500GB drive? You can. Windows can't do this for most files, but Ztree knows the formatting of many programs. I put that Ztree on a STICK (the license covers five machines), and can plug it into anything.
So 64-bit or 32-bit (oddly enough, the latter works better on 64-bit Win10) and now all my many Win7 machines searches FINALLY work. Hidden files or text or you name it.
Now, if you're not familiar with the interface from DOS, it is a huge learning curve. But if you have to do a lot of file housekeeping and comparing and searching, then the learning curve is worth it.
Two things no Windows junkie should ever be without: 1) a Linux stick to boot when Windows goes wonky or isn't advanced enough for current functions/drivers/drivers/peripherals.. and 2) ZtreeWin.
